I have run across an issue I am having with it though, which hopefully somebody can shed some light on.

I have placed the template tag for this plugin in my header.php template file. Basically I am using it to display a custom message over an image in the header.

This works beautifully on every page apart from the blog page. In settings -> reading -- I have static home page set to a page template, and I have created a page called blog, which loads up the main blog index.

The content block editor does not appear when I go into that blog page.

Is this because in reality this page doesn't exist? It is working on all my other pages even on individual blog posts, just the blog page which isn't working?

As this is setup in my header.php file I am not going to be able to hard code the message in for that one page, so I need a solution if this is possible or not.
